  • Methods of mining – Te Ara Encyclopedia of New Zealand

    Gold mining was rough, physical work. Where alluvial gold was very rich, it could be obtained with a shovel and pan. However, pans were used mainly for prospecting. Simple machines known as cradles (often made from wooden liquor boxes) were rocked back and forth – the heavier gold collecting on matting on the cradle base. Sluice boxes. Riffle or sluice boxes were the main methods of
